The United States Geological Survey slightly downgraded Sunday's quake after initially calling it 7.0-magnitude. Strong aftershocks ranging from 5.4- to 4.3-magnitude followed the main quake, the USGS said.

Indonesia's Tsunami Early Warning System had issued a tsunami warning after the main quake but it was later lifted, according to the country's National Disaster Management Agency.
